Description

Technical Field

[0001] This utility model relates to the field of electric water heaters. Background Technology

[0002] Current electric kettles typically heat water inside the inner tank before dispensing it from the spout for drinking. Due to the large volume of the inner tank, heating time is long, impacting user experience. To address this, some technologies propose placing a kettle on the outside of the kettle, directly below the spout, to collect and heat the water. However, during this process, water easily drips onto the kettle, causing water stains. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide an electric water bottle that can prevent water droplets from falling onto the body and causing pollution.

[0004] One embodiment of this utility model provides an electric water bottle, comprising: a body with a water outlet; an inner liner disposed inside the body and connected to the water outlet; a kettle disposed outside the body, the inner liner also connected to the kettle's inner liner via a pipe from the bottom of the kettle; a first pump body disposed on the pipe connecting the kettle's inner liner and the inner liner of the body, the first pump body being able to introduce a portion of the liquid in the inner liner of the body into the kettle's inner liner for heating in the kettle; a low liquid level detection device disposed at the bottom of the kettle's inner liner for detecting whether the liquid level in the kettle's inner liner is below a first set height; and a control circuit board electrically connected to the first pump body and the low liquid level detection device, the control circuit board being able to control the first pump body to introduce the liquid in the inner liner of the body into the kettle's inner liner when the low liquid level detection device detects that the liquid level is below the first set height.

[0005] The electric kettle provided in this embodiment allows liquid in the inner liner of the kettle to enter the inner liner of the kettle directly through a pipe. During the process of pouring liquid into the kettle, the liquid will not leak out, preventing liquid from dripping onto the kettle body and splashing out of the inner liner. Furthermore, a low-liquid-level detection device is installed at the bottom of the inner liner. When the user needs to boil water, the low-liquid-level detection device first determines the liquid level in the inner liner. If the liquid level is lower than a first set height, the first pump is promptly controlled to introduce liquid from the inner liner into the inner liner before the kettle is started to boil water, effectively preventing dry-boil problems.

[0006] Furthermore, in some embodiments, the electric kettle also includes a high-level detection device, disposed at the upper part of the inner liner, for detecting whether the liquid level inside the inner liner has reached a second preset height. A control circuit board is also electrically connected to the high-level detection device, and the control circuit board can also control the first pump to stop operating when the high-level detection device detects that the liquid has reached the second preset height. This design effectively prevents the first pump from pumping too much liquid into the inner liner, avoiding liquid overflow during heating. The high-level and low-level detection devices work together to control the high and low liquid levels inside the inner liner.

[0007] Furthermore, in some embodiments, the electric kettle also includes a timer electrically connected to both the first pump body and the control circuit board. The timer detects whether the running time of the first pump body has reached a set duration, and the control circuit board can also control the first pump body to stop running when the timer detects that the set duration has been reached. Thus, by controlling the running time of the first pump body to control the amount of liquid injected into the kettle liner, excessive liquid can be prevented from being pumped into the kettle liner, avoiding liquid overflow during heating and preventing liquid outflow. The timer and low liquid level detection device work together to control the high and low liquid levels inside the kettle liner, and the timer has a simple structure and low cost.

[0008] Furthermore, in some embodiments, the electric kettle also includes a valve body disposed on the pipe between the inner liner of the kettle and the inner liner of the kettle body. A control circuit board is electrically connected to the valve body. The control circuit board can control the valve body to open when the low liquid level detection device detects that the liquid level is below a first set height, and can also control the valve body to close when the high liquid level detection device detects that the liquid level reaches a second set height, or control the valve body to close when a timer detects that a set duration has elapsed, thereby blocking the flow of liquid in the pipe between the inner liner of the kettle and the inner liner of the kettle body. Thus, after the valve body is closed, it prevents the liquid in the pipe from flowing due to the height difference between the inner liner of the kettle and the inner liner of the kettle body, ensuring that the liquid in the inner liner of the kettle body does not overflow, nor does it prevent the liquid in the inner liner of the kettle body from flowing back into the inner liner of the kettle body due to the liquid level in the inner liner of the kettle body being lower than the liquid level in the inner liner of the kettle body.

[0009] Furthermore, in some embodiments, a support platform is provided on the outer bottom of the body, and the kettle can be detachably placed on the support platform. The support platform has a water supply port communicating with the inner liner of the body, and the bottom of the kettle has a water inlet communicating with the inner liner. When the kettle is removed from the support platform, the water inlet closes; when the kettle is placed on the support platform, the water inlet and water supply port are connected and open. This allows users to easily move the smaller kettle to a designated location to pour water and prevents liquid from overflowing when the kettle is removed from the body.

[0010] Furthermore, in some embodiments, a first electrical coupler is provided at the bottom of the kettle, and a second electrical coupler capable of being electrically connected to the first electrical coupler is provided on the support platform. The water inlet is located in the middle of the first electrical coupler, and the water outlet is located in the middle of the second electrical coupler. The structure is compact, and the pipes occupy little space.

[0011] Furthermore, in some embodiments, the water inlet communicates with the inner liner of the kettle through a through hole on the bottom wall of the inner liner. Here, the through hole can be positioned opposite the water inlet, resulting in a simple structure and ease of manufacturing.

[0012] Furthermore, in some embodiments, a handle is provided on the outside of the kettle, and a water inlet pipe is provided inside the handle. The water inlet pipe passes through the upper end of the handle and communicates with the inner liner of the kettle, while the lower end of the water inlet pipe extends to the bottom of the inner liner and communicates with the water inlet. Compared with opening a through hole in the bottom wall of the inner liner, the risk of water leakage from the inner liner can be reduced.

[0013] Furthermore, in some embodiments, the support platform includes a water-receiving area and a support area arranged side by side, with the kettle detachably mounted on the support area and the spout positioned above the water-receiving area. This allows users to conveniently place containers such as cups in the water-receiving area to collect liquid flowing from the spout without interference from the kettle.

[0014] Furthermore, in some embodiments, the inner liner and the kettle are arranged side by side in a horizontal direction. The bottom of the inner liner has an outlet. The electric kettle also includes: a three-way pipe, the first port of which is connected to the outlet of the inner liner, the second port of which is connected to the inlet of a first pump body, and the outlet of the first pump body is connected to the inner liner via a pipe; and a second pump body, the third port of which is connected to the inlet of the second pump body, and the outlet of the second pump body is connected to the spout via a pipe. This design allows for the supply of liquid to both the spout and the kettle by simply opening one outlet at the bottom of the inner liner, simplifying manufacturing and reducing the risk of leakage at the bottom of the inner liner.

[0015] Furthermore, in some embodiments, the inner liner of the kettle and the inner pot are arranged side by side in the horizontal direction. The bottom of the inner liner has an outlet. The electric kettle also includes a three-way valve. The first valve port of the three-way valve is connected to the outlet of the inner liner of the kettle through a first pipe. The second valve port of the three-way valve is connected to the inner liner of the kettle through a second pipe. The third valve port of the three-way valve is connected to the spout through a third pipe. The first pump body is arranged on the first pipe.

[0016] In these embodiments, a three-way valve is used to connect the inner liner of the machine, the inner liner of the kettle, and the spout separately. Compared with connecting them through separate pipes, this reduces the number of pipes, the space occupied by the pipes, and simplifies the pipe layout. Moreover, by placing the first pump body on the first pipe, and coordinating with the different opening and closing states of the three-way valve, only one pump body is needed to pump liquid to the inner liner of the kettle and the spout separately, reducing the number of parts and lowering costs.

[0017] Furthermore, in some embodiments, the electric kettle also includes: a temperature sensor disposed at the bottom of the inner liner to detect whether the temperature of the liquid inside the inner liner has reached the set temperature; a control circuit board is also electrically connected to the temperature sensor and the kettle's heating element, and the control circuit board can also control the kettle's heating element to stop operating when the temperature sensor detects that the temperature has reached the set temperature. This avoids dry burning of the kettle due to prolonged heating and saves energy.

[0040] The following will combine Figures 1 to 5 This invention introduces an electric water bottle provided by an embodiment of the present invention.

[0041] like Figures 1 to 5As shown, one embodiment of this utility model provides an electric water bottle, which includes: a body 100 with a water outlet 110; an inner liner 200 disposed inside the body 100 and connected to the water outlet 110; a kettle 300 disposed outside the body 100, the inner liner 200 also connected to the inner liner 310 of the kettle 300 from the bottom of the kettle 300 via a pipe; and a first pump body 400 disposed on the pipe connecting the inner liner 310 and the inner liner 200. The device 300 can introduce a portion of the liquid in the inner liner 200 into the inner liner 310 for heating in the kettle 300; a low liquid level detection device 320 is located at the bottom of the inner liner 310 to detect whether the liquid in the inner liner 310 is below a first set height; a control circuit board is electrically connected to the first pump body 400 and the low liquid level detection device 320 respectively, and the control circuit board can control the first pump body 400 to introduce the liquid in the inner liner 200 into the inner liner 310 when the low liquid level detection device 320 detects that the liquid is below the first set height.

[0042] The electric kettle provided in this embodiment allows liquid in the inner liner 200 to directly enter the inner liner 310 of the kettle 300 through a pipe. During the process of pouring liquid into the kettle 300, the liquid will not leak out, preventing dripping onto the body 100 and splashing from the inner liner 310. Furthermore, it reduces the possibility of liquid contamination from contact with air, improving product safety. Moreover, a low-level detection device 320 is installed at the bottom of the inner liner 310. When the user needs the kettle 300 to boil water, the low-level detection device 320 first determines the liquid level in the inner liner 310. If the liquid level is lower than a first set height, the first pump 400 is promptly controlled to introduce liquid from the inner liner 200 into the inner liner 310 before the kettle 300 is controlled to boil water, effectively preventing dry-boil problems.

[0043] Furthermore, in some embodiments, such as Figure 4 As shown, the electric kettle also includes a high-level detection device 330, which is installed on the upper part of the inner liner 310. This device detects whether the liquid level inside the inner liner 310 has reached a second set height. A control circuit board is also electrically connected to the high-level detection device 330. The control circuit board can also control the first pump 400 to stop operating when the high-level detection device 330 detects that the liquid has reached the second set height. This design effectively prevents the first pump 400 from pumping too much liquid into the inner liner 310, avoiding liquid overflow during heating. The high-level detection device 330 and the low-level detection device 320 work together to control the high and low liquid levels inside the inner liner 310.

[0044] In practical applications, the high liquid level detection device 330 and the low liquid level detection device 320 can have the same structure for easy manufacturing. Of course, different components can also be used.

[0045] Furthermore, in some embodiments, the electric kettle also includes a timer (not shown in the figure), electrically connected to the first pump body 400 and the control circuit board respectively. The timer is used to detect whether the running time of the first pump body 400 has reached a set duration. The control circuit board can also control the first pump body 400 to stop running when the timer detects that the set duration has been reached. In this way, by controlling the running time of the first pump body 400 to control the amount of liquid injected into the inner liner 310, it is possible to effectively prevent the first pump body 400 from pumping too much liquid into the inner liner 310, avoiding liquid overflow during heating and preventing liquid outflow. The timer and the low liquid level detection device 320 work together to control the high and low liquid levels in the inner liner 310, and the timer has a simple structure and low cost.

[0046] Furthermore, in some embodiments, such as Figure 4 and Figure 5 As shown, the electric kettle also includes a valve body 600, which is installed on the pipe between the inner liner 310 and the inner liner 200 of the kettle. A control circuit board is also electrically connected to the valve body 600. The control circuit board can open the valve body 600 when the low liquid level detection device 320 detects that the liquid level is below a first set height, and can also close the valve body 600 when the high liquid level detection device 330 detects that the liquid level reaches a second set height, or when the timer detects that the set duration has been reached, thereby blocking the connection between the inner liner 200 of the kettle and the inner liner 310 of the kettle. Thus, after the valve body 600 is closed, it can prevent the liquid in the pipe from flowing due to the height difference between the liquid level H1 in the inner liner 200 of the kettle and the liquid level H2 in the inner liner 310 of the kettle, ensuring that the liquid in the inner liner 310 will not overflow, nor will it cause the liquid in the inner liner 310 to flow back into the inner liner 200 of the kettle due to the liquid level in the inner liner 200 being lower than that in the inner liner 310 of the kettle.

[0047] The valve body 600 can be either a two-way valve or a three-way valve, as long as it can block the flow of the pipe between the inner liner 200 of the machine body and the inner liner 310 of the kettle. As an example, the valve body 600 is a two-way solenoid valve.

[0048] Furthermore, in some embodiments, such as Figure 1 , Figure 2 and Figure 4As shown, a support platform 120 is provided on the bottom outer side of the body 100. The kettle 300 is detachably placed on the support platform 120. The support platform 120 is provided with a water inlet 1221 that communicates with the inner liner 200 of the body. The bottom of the kettle 300 is provided with a water inlet 350 that communicates with the inner liner 310 of the kettle. When the kettle 300 is removed from the support platform 120, the water inlet 350 is closed. When the kettle 300 is placed on the support platform 120, the water inlet 350 and the water inlet 1221 are connected and conductive. This allows the user to easily move the smaller kettle 300 to a designated location to pour water and prevents liquid from flowing out when the kettle 300 is removed from the body 100.

[0049] As an example, the support platform 120 protrudes outward from the bottom of the outer side of the body 100, making it easy for users to observe the position of the support platform 120 where a kettle 300 or a water cup or other container is placed.

[0050] Furthermore, in some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, a first electrical coupler 360 is installed at the bottom of the kettle 300, and a second electrical coupler 1222, which can be electrically connected to the first electrical coupler 360, is installed on the support platform 120. The water inlet 350 is located in the middle of the first electrical coupler 360, and the water supply outlet 1221 is located in the middle of the second electrical coupler 1222. The structure is compact and the pipes occupy little space.

[0051] As an example, such as Figure 3 As shown, the water inlet 350 is connected to the inner liner 310 through a through hole on the bottom wall of the inner liner 310. This through hole can be positioned opposite to the water inlet 350, resulting in a simple structure and easy manufacturing.

[0052] As an example, the kettle 300 has a handle on the outside, and a water inlet pipe inside the handle. The water inlet pipe passes through the upper end of the handle and connects to the inner liner 310 of the kettle. The lower end of the water inlet pipe extends to the bottom of the inner liner 310 and connects to the water inlet 350.

[0053] In this example, the liquid in the inner liner enters the water inlet pipe inside the handle through the water supply port 1221 on the second electrical coupler 1222 and the water inlet 350 on the first electrical coupler 360, and then enters the inner liner 310 through the water inlet pipe. Compared with opening a through hole on the bottom wall of the inner liner 310 to connect the water inlet 350, the risk of water leakage at the bottom of the inner liner 310 can be reduced, and the probability of water entering the first electrical coupler 360 can be reduced.

[0054] Specifically, a through hole can be made in the top side wall of the inner liner 310, allowing the water inlet pipe to be directly connected to the through hole. Alternatively, the inner liner 310 can have a lid on top, with a water inlet channel inside the lid (not shown in the figure). One end of the water inlet pipe connects to the water inlet channel on the lid, and the other end of the water inlet channel penetrates the bottom wall of the lid and connects to the inner cavity of the inner liner 310, allowing liquid to enter the inner liner 310 through the water inlet channel of the lid.

[0055] In addition, the first electrical coupler 360 can be electrically connected to the components to be powered on the kettle 300, such as the kettle heating element fixed to the bottom of the kettle liner 310, and the low liquid level detection device 320 and temperature sensor 340 fixed to the bottom of the kettle liner 310, etc., which will not be listed here.

[0056] In addition, to prevent liquid from leaking out of the inner liner 310 through the inlet 350 after the kettle 300 moves away from the support platform 120, a switch valve can be installed at the inlet 350 to ensure that the valve body 600 automatically closes when the kettle 300 moves away from the support platform 120. A switch valve can also be installed at the water supply outlet 1221 to prevent liquid from overflowing from the water supply outlet 1221.

[0057] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the support platform 120 includes a water receiving area 121 and a support area 122 arranged side by side. The kettle 300 is detachably mounted on the support area 122, and the spout 110 is positioned above the water receiving area 121. This allows users to conveniently place containers such as cups in the water receiving area 121 to collect liquid flowing from the spout 110 without interference from the kettle 300.

[0058] Furthermore, in some embodiments, such as Figure 4 and Figure 5 As shown, the inner liner 200 and the kettle 300 are arranged side by side in a horizontal direction. The bottom of the inner liner 200 has an inner liner outlet 210. The electric kettle also includes: a three-way pipe, the first port of which is connected to the inner liner outlet 210, the second port of which is connected to the inlet of the first pump body 400, and the outlet of the first pump body 400 is connected to the inner liner 310 through a pipe; and a second pump body 500, the third port of which is connected to the inlet of the second pump body 500, and the outlet of the second pump body 500 is connected to the spout 110 through a pipe. With this design, only one inner liner outlet 210 needs to be opened at the bottom of the inner liner 200 to supply liquid to both the spout 110 and the inner liner 310, which is convenient to manufacture and reduces the risk of water leakage at the bottom of the inner liner 200.

[0059] The valve body 600 can be installed on the pipe between the second port of the three-way pipe and the inlet of the first pump body 400, or on the pipe between the outlet of the first pump body 400 and the inner liner 310, to prevent liquid backflow in the inner liner 310.

[0060] Additionally, a valve body 600 may or may not be installed on the pipe between the inner tank 200 and the spout 110. For example, the highest point of the pipe connecting the spout 110 and the inner tank 200 may be higher than the inner tank 200. This way, after the user stops the water flow from the electric kettle, the liquid in the inner tank 200 will not continue to flow to the spout 110, preventing liquid from accidentally flowing out of the spout 110.

[0061] Furthermore, in some embodiments, the inner liner 200 and the kettle 300 are arranged side by side in the horizontal direction. The bottom of the inner liner 200 has an inner liner outlet 210. The electric kettle also includes a three-way valve (not shown in the figure). The first valve port of the three-way valve is connected to the inner liner outlet 210 through a first pipe. The second valve port of the three-way valve is connected to the inner liner 310 through a second pipe. The third valve port of the three-way valve is connected to the spout 110 through a third pipe. The first pump body 400 is disposed on the first pipe.

[0062] In these embodiments, a three-way valve is used to connect the inner liner 200, the inner pot liner 310, and the spout 110 respectively. Compared with connecting them through separate pipes, this reduces the number of pipes, the space occupied by the pipes, and simplifies the pipe layout. Moreover, by placing the first pump body 400 on the first pipe, and coordinating with the different opening and closing states of the three-way valve, only one pump body is needed to pump liquid to the inner pot liner 310 and the spout 110 respectively, reducing the number of parts and lowering costs.

[0063] In practical applications, when it is necessary to pump liquid into the inner liner 310, the first and second valve ports of the three-way valve can be opened, while the third valve port is closed. This allows the first pump body 400 to introduce liquid from the inner liner 200 into the inner liner 310. When it is not necessary to pump liquid from the inner liner 200 into the spout 110, the first and third valve ports of the three-way valve can be opened, while the second valve port is closed. This allows the first pump body 400 to introduce liquid from the inner liner 200 into the spout 110.

[0064] Furthermore, in some embodiments, such as Figure 3As shown, the electric kettle also includes: a temperature sensor 340, located at the bottom of the inner liner 310, used to detect whether the temperature of the liquid inside the inner liner 310 has reached the set temperature; a control circuit board is also electrically connected to the temperature sensor 340 and the heating element of the kettle 300, and the control circuit board can also control the heating element to stop operating when the temperature sensor 340 detects that the temperature has reached the set temperature. This prevents the kettle 300 from dry-burning due to prolonged heating, thus saving energy.

[0065] Furthermore, in some embodiments, the volume of the inner liner 310 is smaller than the volume of the inner liner 200. This allows the liquid in the inner liner 310 to be heated quickly when boiling water is needed; compared to directly heating the liquid in the inner liner 200, the liquid in the inner liner 310 can boil rapidly, facilitating the electric kettle's ability to quickly provide boiling water.

[0066] Furthermore, the kettle 300 includes an inner liner 310 and a heating element. The inner liner 310 is used to hold liquid, and the heating element is used to heat the liquid inside the inner liner 310. The heating element can be located at the bottom or outer periphery of the inner liner 310 and moves synchronously with the inner liner 310. Alternatively, the heating element can be located within the body 100, heating the kettle body at intervals. The specific arrangement depends on the specific structure of the heating element.

[0067] As an example, the kettle heating element includes a heating element fixed to the outer side of the bottom wall of the kettle liner 310.

[0068] As an example, the kettle heating element includes an electric heating film, which is fixed to the outer side of the bottom wall or the outer side of the side wall of the kettle inner liner 310.

[0069] As an example, the kettle heating element includes an electromagnetic coil disposed within the body 100 and below the kettle liner 310, which has a magnetic conductive element or is made of a magnetic material to achieve electromagnetic heating.

[0070] Furthermore, in some embodiments, the electric water bottle also includes an inner tank heating element for heating the liquid in the inner tank 200. This allows the inner tank heating element to directly heat the liquid in the inner tank 200 when a large amount of boiling water is needed, or when heating time is not a concern. The inner tank 200 then supplies liquid to the user through the spout 110, thus enabling the electric water bottle to provide a large volume of liquid. The electric water bottle can perform corresponding heating operations according to the user's needs.

[0071] Furthermore, the heating element for the inner liner can be located at the bottom or outer periphery of the inner liner 200, or it can be located within the body 100, heating the inner liner 200 at certain intervals. The specific location depends on the structure of the heating element. The specific structure of the inner liner heating element can refer to the heating element of the kettle mentioned above; the two can be the same, for example, both being heating elements, or they can be different.

[0072] Furthermore, in some embodiments, the body 100 has an inner liner receiving cavity, and the inner liner is detachably disposed within the inner liner receiving cavity. This facilitates the removal of the inner liner, the filling of water into the inner liner, and the cleaning of the inner liner.

[0073] Furthermore, in the case where the electric water bottle includes a heating element inside the inner liner, a third electrical coupler is provided to electrically connect the bottom of the inner liner to the heating element, and a fourth electrical coupler is provided on the cavity wall of the inner liner housing cavity to cooperate with the third electrical coupler. This facilitates the supply of power to the heating element inside the inner liner.

[0074] Furthermore, the third electrocoupler has an outlet in its middle that communicates with the inner cavity of the inner tank, and the fourth electrocoupler has a through-hole in its middle that connects to the outlet. To prevent liquid from leaking out of the inner tank through the outlet after the inner tank moves 100mm away from the machine body, a switch valve can be installed at the outlet to ensure that it automatically closes when the inner tank moves 100mm away from the machine body. A switch valve can also be installed at the through-hole to prevent liquid from overflowing into the inner tank's cavity.

[0075] Furthermore, the top of the body 100 has a top cover that can be opened and closed to accommodate the inner liner. When the top cover of the body 100 is open, the inner liner can be removed from the top of the body 100.

[0076] Furthermore, in some embodiments, the kettle 300 has a removable stewing pot or filter. This allows the kettle 300 to function as both a health-preserving kettle and a teapot, improving the user experience.

[0077] Furthermore, in some embodiments, the kettle 300 also includes an outer shell, an inner liner 310 located inside the outer shell, and a heating element located inside the outer shell and at the bottom of the inner liner 310. The kettle 300 is not a single-layer structure and has a certain degree of heat insulation. In addition, the sidewalls of the inner liner 200 can also be a double-layer structure, providing a certain degree of heat insulation.

[0078] Furthermore, in some embodiments, the outer top of the body 100 has a protruding display and operation component, which is located directly above the support platform 120. The water outlet 110 is located at the bottom of the display and operation component, which facilitates downward water discharge. Moreover, the display and operation component can cover the water outlet 110, resulting in a better appearance.

[0079] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
